  • Patent number: 10412083
    Abstract: A plurality of beacons that do not include any service set identifiers may be broadcast from an access point. A request concerning association with the access point may be sent wirelessly from a user device and received at the access point. A unique service set identifier (SSID) for the requesting user device may be generated, and information regarding the unique SSID may be transmitted to the requesting user device. A subsequent association request from the requesting user device may include the unique SSID.

  • Patent number: 10123257
    Abstract: According to embodiments of the invention, a first wireless access point discovers a second wireless access point, the first wireless access point tunes its radio and privacy settings, without user input, based upon parameters automatically exchanged in response to the discovery of the second wireless access point, and a secure direct wireless connection is established between the first and second wireless access points using the radio and privacy settings. Adding the first wireless to an existing mesh network includes a determination of the best available direct wireless connection.

  • Publication number: 20170289837
    Abstract: A wireless local area network (WLAN) access point may receive a steering policy from a WLAN controller, the steering policy matching various data rate capabilities to various quality of service (QoS) levels. When a client device attempts to connect to the access point (AP), the AP responds via a default virtual access point (VAP) so that the client device transmits its client data rate capability to the AP via association request. The AP then checks the steering policy and either allows the connection to the default VAP if the QoS of the default VAP matches the client data rate or identifies a second VAP (which the AP may generate if it doesn't already exist) whose QoS does match the client data rate. The AP may then initiate WLAN communications between the client device and the matching VAP. Client devices with higher data rate capabilities may thus receive higher priority.

  • Publication number: 20150334598
    Abstract: A centralized wireless LAN load balancing mechanism is described herein. In one embodiment, in response to a request for entering a wireless network from a wireless station and forwarded from multiple access points (APs) of the wireless network, a network access device coupled to the multiple APs determines a load for each of the APs. The network access device then selects one of the APs based on the determined loads of the APs and instructs the selected AP to associate with the wireless station. The network access device further instructs the remaining APs to reject the request. Other methods and apparatuses are also described.
